Abstract

The invention discloses an electric device with a hidden antenna comprising a metal frame, a substrate, an upper casing and a lower casing, wherein the upper casing, the metal frame and the lower casing form a cavity to store the substrate. The lower surface of the metal frame has a groove, wherein the hemline of the groove has a feed-in end, and both sides of the groove form a first short circuit end and a second short circuit which electrically connects to a metal surface of the substrate. Thereby, the metal frame uses the first short circuit end and the second short circuit end and feed-inend to form a half wave cycle antenna. Thus the electric device can use the metal frame to receive and transmit an electromagnetism signal.
